Endeavour Cylindrical Tourbillon

H. Moser & Cie. Endeavour Cylindrical Tourbillon MB&F Off-White, reference 1810-1203, is a rare collaborative timepiece that blends H. Moser & Cie.’s minimalist fumé dial language with MB&F’s three-dimensional mechanical architecture. Limited to only 15 pieces, this Off-White edition is housed in a 42 mm stainless steel Endeavour case, topped by a high domed sapphire crystal that gives full visibility to the elevated flying tourbillon at 12 o’clock. The case measures 19.5 mm thick including the crystal, with a sapphire exhibition caseback and 30 metres of water resistance. The dial is finished in Off-White fumé with a sunburst pattern, offering a clean contrast to the exposed mechanical display. Hours and minutes are shown on a transparent sapphire sub-dial tilted at 40 degrees, a clear MB&F-inspired design element, with blued leaf-shaped hands specific to this reference.

Power is supplied by the HMC 810 automatic manufacture calibre, a three-dimensional movement fitted with a one-minute flying tourbillon and cylindrical hairspring. The movement comprises 184 components, 29 jewels, beats at 21,600 vibrations per hour and provides a minimum 72-hour power reserve through a bi-directional pawl winding system. Finished with bevelled bridges, Moser stripes and an 18-carat gold oscillating weight engraved with the H. Moser & Cie. logo, this piece is a highly technical and visually distinctive expression of modern independent watchmaking.
